The best thing would be shorter hours for the same total pay. It has the freedom to add more hours if they want more income, spend more time with the people or hobbies they love if they don’t, and makes whatever headaches the job may include more tolerable. If that’s not an option, it depends on what the headache is. Taking 100g off the scanner I have to lift 50 times each day vs taking home an extra, let’s say 5~10% pay? I’ll take the cash. It’d let me take more time off, do more fun things, etc. and the weight isn’t that much unless you have a prior condition. If it’s something that will make it so I can eliminate the need to scan anything and just get to the more important parts of the job, maybe.

Let’s be real here, though. If the option was there, any slackager (slacker manager) is going to do neither because that’d take effort. Any company serving manager is going to just not give the raise and tell the employees they complain too much and should be grateful for the work. And any human serving manager will be fired for wasting company funds on unecessary comforts or raises.
